Salt Spray Testing is a standardized corrosion test used to evaluate the durability and corrosion resistance of coated or treated materials. As per ASTM B117 and ISO 9227 standards, specimens are placed in a controlled salt fog chamber where a 5% sodium chloride solution is atomized at a constant temperature, typically 35°C. The exposure duration varies based on material requirements. This accelerated test simulates harsh environmental conditions, helping manufacturers assess coating quality, predict product lifespan, and ensure compliance with industrial performance and safety standards.
